Have you been annoyed by the "SmartSync" battery-saving feature found on HTC's newest phones? If you're not familiar with this aspect of Sense 4.0, that might make, well, sense. HTC has been fairly quiet about how exactly its battery optimizations in Sense work, but SmartSync is a big part of it, especially when it comes to saving juice overnight.

All Sense 4 phones (HTC One X, XL, S, V and EVO 4G LTE) utilize this feature to reduce battery consumption in the wee-hours, specifically from 12AM to 7AM.

This is Sprint's version of the HTC One X. HTC's much publicized "One" branding strategy survived a grand total of two carriers in the US - Sprint kicked it to the curb in favor of the aforementioned alphabet-soup-style naming convention. Keep in mind the original Evo was actually called the "HTC Evo 4G," so you're going to need to be detail oriented when talking about the Evo line.

Last night we got some hands-on time with HTC's new family of smartphones - the One series. While we didn't get a hands-on video with the One X (largely due to a dead battery), we did spend a fair amount of time with the One S, which shares most of its hardware with its larger sibling.

The main difference between the two lies in the displays. The One S packs a 4.3" SAMOLED qHD display (540x960), while the One X has HTC's new 4.7" S-LCD2 HD screen (1280x720).
